Unrepaired DNA Damage Can Persist for Years and Lead to Cancer Mutations

While most known types of DNA damage are fixed by our cells’ in-house repair mechanisms, some forms of DNA damage evade repair and can persist for many years, new research shows. This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer.

New Discovery Sheds Light on How Monoamines Regulate Brain Rhythms

A collaborative effort between Mount Sinai and Memorial Sloan Kettering Cancer Center has shed valuable light on how monoamine neurotransmitters such as serotonin, dopamine, and now histamine help regulate brain physiology and behavior through chemical bonding of these monoamines to histone proteins, the core DNA-packaging proteins of our cells.

Weak Molecular Interactions Trigger Autophagy in Cells

Recycling takes place in our cells at all times: in a process called autophagy, cell components that are no longer needed are enclosed by membranes and broken down into their basic building blocks.
